I noticed that the new 2004 edition of ASME B31.3 now references ASME
B16.48 1997 for blinds, however, the blind thickness calculation in section
304.5.3 of B31.3 is still the same.  In some cases, the B31.3 calculation
requires a thicker blind than specified in B16.48.  Now that it's listed
as a reference standard in B31.3, what does this mean?  Does it mean the
B31.3 recognizes B16.48 thickness as being acceptable to the flange rating
of the same material with the same corrosion allowance?
